New Zealand White (Rabbit) — Amelogenesis imperfecta, FAM83H-related (hereditary; OMIA-verified breed predisposition)

Claims

  • Breed: New Zealand White (Rabbit)
  • Disorder:
  • Summary: Zhang et al. (2022): Fam83h mutations cause human amelogenesis imperfecta (AI), an inherited disorder characterized by severe hardness defects in dental enamel. ... a large deletion of the Fam83h gene (900 bp) was generated via a dual sgRNA-directed CRISPR/Cas9 system in rabbits. This study involves genetically modified organisms (GMO).
  • Clin feat: Zhang et al. (2022): Abnormal tooth mineralization and loose dentine were found in homozygous Fam83h knockout (Fam83h-/-) rabbits compared with WT rabbits. In addition, reduced hair follicle counts in dorsal skin, hair cycling dysfunction and hair shaft differentiation deficiency were observed in Fam83h-/- rabbits. Moreover, X-rays and staining of bone sections showed abnormal bending of the ulna and radius and an ulnar articular surface with insufficient trabecular bone in Fam83h-/- rabbits.
  • Defect: yes
